“You may have been free, you loved loving your lie, fate had its own scheme, crushed like a bug you still die,” Keyes wrote.

At another point he writes about the “nervous laugh as it burst like a pulse of blood from your throat. There will be no more laughter here.”

The arrest of Keyes, 34, on March 12, 2012 for the murder of Alaskan barista Samantha Koenig ended more than a decade of traveling around the country to find victims to kill or to prepare for future crimes by burying murder kits of weapons, cash and tools to dispose of bodies. Since March, he had been slowly telling police about his hidden life and how he operated. But the tale abruptly ended when Keyes committed suicide in his jail cell on Dec. 1.

Police are now left trying to fill in the details of Keyes’ life. Police believe he killed between eight and 12 people, including Koenig, but only three victims have been definitively tied to Keyes so far.

The FBI released Keyes’ four-page document on Wednesday, describing it as “a combination of pencil and ink on yellow legal pad.” The pages were discovered under Keyes’ body, “illegible and covered in blood,” the FBI said.

The papers were sent to an FBI laboratory in Virginia for processing and the FBI was able to restore the notes to a mostly legible condition for review and analysis.

“The FBI concluded there was no hidden code or message in the writings,” the FBI said in a news release Wednesday. “Further, it was determined that the writings do not offer any investigative clues or leads as to the identity of other possible victims.”

The FBI said it would not offer any commentary as the meaning of the writings, but the chillingly morbid writings speak for themselves.
